The land division system used for describing the extent of oil and gas interests located in the Northwest Territories, Nunavut or in Canada's offshore area is defined in the Canada Oil and Gas Land Regulations. This land division system consists of a grid system divided into Grid Areas, Sections, and Units – all referenced to the North American Datum of 1927 (NAD27). This data provides the geo-spatial representation of the NAD27 Oil and Gas Grid Areas referenced to NAD83 Datum. The creation of the Oil and Gas Grid Areas geo-spatial file covers areas that are situated in the Northwest Territories, Nunavut or Sable Island as well as submarine areas, not within a province, in the internal waters of Canada, the territorial sea of Canada or the continental shelf of Canada beyond 200 nm zone. The NAD83 grid area boundaries are defined by geodesics joining the four grid area corners. For sections and units, the eastern and western grid area geodesic boundaries are partitioned into 40 equal segments. The northern and southern grid area geodesic boundaries are partitioned into 40, 32 or 24 equal segments, depending on latitude. All internal corners at the section and unit level are defined by the intersections of north-south and east-west geodesics joining corresponding partition points along the northern and southern, and eastern and western, grid area geodesic boundaries.

Provinces and Territories Basemap - Canada Provinces basemap file created to generate boundary polygons for use in small scale, medium and large scales. Simple Grey Basemap - This basemap is only in simple grey and white to be used as a backdrop in applications or geomatics projects. Line features represent provincial and territorial boundaries, international boundaries, exclusive economic zones, arcs extending to the North Pole, state boundaries, Canadian, USA and foreign countries rivers. Polygon features representing waterbodies in Canada, USA and foreign countries.

Canada Center for Mapping and Earth Observation (CCMEO)'s basemap is essential in supporting the Government of Canada’s priorities in areas such as open government, climate change mitigation, Indigenous reconciliation, emergency management, disaster preparedness and response, sustainable natural resource management, infrastructure planning, economy/labour and more. It reinforces CCMEO’s commitment to improving the accessibility, interoperability and integration of geospatial data across Canada. CCMEO currently offers multiple basemap types which include the following found in this series: - Transportation basemap (CBMT) in raster tile format - Transportation basemap (CBMT) in vector tile format EPSG: 3857 (WGS84 Pseudo-Mercator) - Transportation basemap (CBMT) in vector tile format EPSG: 3978 (NAD83 Canada Atlas Lambert) - Digital Elevation Model (DEM) - hillshade basemap (CBME) - Simple grey basemap - Provinces/Territories basemap - Grids (Lat/Long, NTS and UTM) basemap
